RS-232 is a standard for serial communication in telecommunications, transmitting data one bit at a time.
In telecommunications, RS-232 is used for serial communication transmission of data. The RS-232 standard is a protocol used for serial communication, which means that data is transmitted one bit at a time over a single channel. This contrasts with parallel communication, where multiple bits are sent simultaneously across multiple channels. RS-232 is commonly utilized in computer serial ports and for connecting peripheral devices.
